To all 'uf/1.0m itmay/ concern Be it known that I, JOSEPH EL KENNEDY,

a ciiizenoi the United States, residing in the borough ofliliinhattan,city, county, and. State of' New York, have inventedcertain. new and useful Improvements. in`Crushing and PulverizingMachines, of which the fol-y lowing is a specification. i

My iniprovemcnts relate toA crushing and pulverizing mechanism of thegyratoryvtype, and are designed 'to afford .u ,substantial compactstructure of relativelylightweight, in which the shaft is suspended atits upper vend upon an adjustable bearing, and in "of a.' truncatedconical Y idly secured to thc'shuft A, and gyriiti'ng 5(tation.

' in general operation :ind arrangement of 'iai-ts my apparatus is'essentially the,A same :is others of the riitoryclass, consistingerushing'head a, rigi'n an oppositely; inclined convex crushing chamberb, from which therediiced mate-A r lriti-escapes into the 'chute chamberc.

-' turn upon :in iidjustable supportl, mounted iii theuipper frame plate(l. 'Obviously the moet expedient way of 'milking the iSuppor 5i,adjustable is to forni it with a pcriphcmil inzilc screw for enisugciiient with n female screw thread on the upper frame pint-e al, oron the sleeve al', inserted in the izitlcif :is ,shown in thedrawings-,-although l do ,not limit myself in this particiiliirftheessential feiiturc in` this respect being the. provision cf suitablemeans for effect ii* the vertical adjustment or' the annular hearing Thelower portion :clr'l in l e? the vi-entric nimmer, om, gil, et

centric bearing itself is of special construction. Peripherallv asrelated to its axes of rotation it is of convex form, formly curved inthe' are of a circle, and is seated in n correspondingly curvedconcavity l6, inthe sleeve'7, to which the drivf inmgear 8, is secured.The principle involvedis that of the ball the change in inclination ofthe longitudinal'axisof the shaft wit-hin the pre-v scribed or desiredlimits of adjustment'nie,

so slight that it' isnot necessary iii-practicel fivliich' 7D torcsoitto the spheroidzil form,- would be objectionable on account lspace involved. While thus freotoidupt itself to the inclination otlie'shzift A, the eccentric bearing 5, is held against lu eral movementin its sent 6, by onci'irinorc keys 75 9, or'equivalcnt mechanicalexpedients, by which 'it is coupled to the sleeve 7, so as toi rotatetherewith while free to adept itself axially with relation to Vthelongitudinal axis of the shaft.

Thedriving gea-r 8, is rotated by iiieuns of vthe pinion p, .upon tli'epower', shaft I; andthe 'iippiirutlis is provided with thc usuiil' dustguards, &c.`

The sleeve 7, is made in two or more parts v vto admit of the seatingvof thc .lixiii-llycon- Vex eccentric bearing 5, the ports of the"sleeve lieing rigidly secured together, und 1 to theV driving gear 8.The essential fentiire being .the axiiil' centric bearing :3, withrelation to its seat 6,

7, it is obvious that viii'ious modifications ma'y be resortedto-without departing from the spirit and intent of my v invention inthis respect. '.llius by way of' 95 illustration, in Fig. 3, the use ofkeys isA dispensed ,'with by making .the eccentric hearing with recesses10, into which lit ribsl 1l, in the sont (i, sotliat the sleeve andcccenti'ic .beui'ing the eccentric hearing is free to 'iidupt itself totlieincliiizition'of the shaft. It will thus be seen that :idistinguishing characteristic.'

. of my invention consists .in milking the'eceen ric beoringfor thelower end of the 105 shaft rotatable with the sleeve in whichl it ismountedl by means whichallow Suid ec`- centi-ic bearing-t0 adapt itselffreely to varif ations ininclination of saidjs'haft. l
